Abstract
A method for producing a machine direction and cross-machine direction elastic laminate includes the steps of providing a one direction elastic laminate material including at least one elastic layer and one facing layer and having a single direction of elasticity and coursing the one direction elastic laminate material through at least one stretching apparatus, such that the stretching apparatus stretches the laminate material in a direction perpendicular to the single direction of elasticity of the elastic laminate material, thereby producing a material that extends in a direction perpendicular to the direction of elasticity and also extends the elastic performance of the laminate in the single direction of elasticity.
